I don't think the musician/startup analogy works. Regardless of the legality of using certain drugs and prescriptions, sports players are competing against each other for a certain output. Musicians and entrepeneurs are creating a product, whether it be music or a company, that stands alone irrespective of the lengths they went to achieve that creation. The people consuming that product aren't suffering because someone else did the drugs, unlike the cyclist who is competing against a doped up competitor or the investor who doesn't do insider trading like others do.
